TO ALL WHOM IT MAY (LONCERN:l

` Be it known that I, Geenen W. SEYMOUR, of Whitneys Point, in the county of Broome, and State of New York, have invented a new and useful Improvement on Carringe-Wheelsj and I do hereby declare that the following is a full, clear, and exact description of the sume, reference being had'to the accompanying dre-W` ings, making!!I port of this specilicatiomin which- Figure 1 isa perspective view representing the wheel and axle..` f i Figure 2 shows tho wheel in a horizontal position with thooxle-box and adjusting-.nut detached- Similar letters of reference indicate correspondingparts in each figure. Y

` The nature of my invention 'consists of la metallic' earragewheel with an adjustable h'ub comprising two movable rings, which support the a'xlefbox, each arrying an equal number of'spokes centrmgin the rim. -Thse'ripgs are seta. suiiicient distancezapajrttolgi-ve the requireclbracing angle'to thespokes` andmaiy be carnpressed ir-loosened to 'a'certain extent, by meansof a nut and screw on the outer endbf theaxle-box, forthe purpose of regulating thcptension of'the spokes. i To enable others to make anduse my invention, `I will' proceed to ldescribe its construction and operation. I constructthe rim A and spokes of .'my carriage-wheel of wroughtiron or steel. The hub-ringsB B may be made of either cast or-wrought iron, and a key-seat cnt for the stationary key on the axle-box E. These key-s ats should bemade loose enough for the rings to move in freely on s'hid axle-box. f I use sixteen spokes t inv the wheel, I drill eight holes in each ring, tap them, and screw in the spokes to their shoulders. -The rim is ,then formed, to the proper diameter andlapped for welding, the holes for the spokes drilled and countersunk. I then place the axle-boxlE into the rings, enterpthe spokes, rivet them, and iveld the lap'ot the rim. I then cut 'a left-handed screw on 'the outer end. of the cylindrical axle-box for the right-hand wheel, and vice versa for the left-hand wheel for altbimble-nut, F, by which the tension of the wheel may be adjusted by oou1- pressing or looscning the rings B B, thereby giving it 'a slight degree of hxsticity. The'wheel is secured on the axle in thc usual manner, by a nut working inside of the thimble-nut F.

In use it is found that my improved wheel works with less jar and noise than those in ordinary' use, und if the joints should become loose from weer brother cause, they may bereadily brought to their proper tensionby of turn of the adjustable nut This'w'heelmay be manufactured at one-qua`rterA less expense. than' the ordinary wheel, and is more durable and perfect in itsoperetien. What I claim, and desireto secure by Letters Patent, is-

Th'e combination and arrangement of? the stationary key I) with the wheclturning the axle-box E, adjustable Atlliinble-mxt F, and movable ringsBV B, ull being constructed substantially as herein described and represented, for the purpose set forth.
